The provisions of this chapter shall pertain only to the disposal of industrial liquid wastes to the public sewers.
(Prior code § 5-4.1001)
A person shall obtain a permit from the city engineer prior to the discharge of industrial wastes to a public sewer. The city engineer shall not grant such a permit unless he finds that sufficient capacity exists in the public sewer to allow for such industrial wastes as determined by the requirements of Section 13.04.660.
A separate permit shall be required for each connection discharging industrial wastes to the public sewer.
For the purposes of this section, discharges resulting from garbage grinders powered by motors of one horsepower or less and grease interceptors installed in restaurants in accordance with the provisions of the plumbing code of the city where such facilities are not required by other provisions of this chapter shall not be considered to be industrial waste discharges.
(Prior code § 5-4.1002)
By following the procedure set forth in Section 13.16.080, the city engineer may recommend the revocation of, and the council may revoke, any permit if, after a public hearing, if a public hearing is requested, or otherwise after due investigation, the council finds:
A. 
A failure of the permittee to correct conditions as required by the city engineer; or
B. 
Conditions which would justify the denial of a permit; or
C. 
Fraud or deceit was employed in obtaining the permit; or
D. 
Any other violation of this chapter or of any condition of any permit, including the one to be revoked, license, or exception granted under this chapter.
(Prior code § 5-4.1003)
The city engineer shall provide printed application forms for the permits required by this chapter, indicating thereon the information to be furnished by the applicant. The city engineer may require, in addition to the information furnished by the printed form, any additional information from the applicant which will enable the city engineer to determine that the proposed disposal complies with the provisions of this chapter.
For the purposes of this section, the city engineer may utilize joint permit application forms under agreements established with other public agencies as provided in Section 13.04.190.
(Prior code § 5-4.1004)
If it appears from the application for any permit required by this chapter that the proposed disposal complies with the provisions of this chapter, the city engineer, upon the receipt of the fees required, shall issue such permit.
(Prior code § 5-4.1005)
Before granting an industrial waste disposal permit to any applicant, the city engineer shall determine:
A. 
That the waste is one which will not damage or destroy the public sewer, or cause an unwarranted increase in the cost of the maintenance of the public sewer, or retard or inhibit the treatment of the sewage; or
B. 
That the waste is one which can be made acceptable by pretreatment.
(Prior code § 5-4.1006)
In the event pretreatment or special facilities are required to make the waste acceptable as provided by this chapter, the applicant for an industrial waste disposal permit may be required to furnish plans showing the method of collection and pretreatment proposed to be used, and a permit shall not be issued until such plans, or required modifications thereof, have been checked and approved by the city engineer.
(Prior code § 5-4.1007)
The city engineer may establish uniform minimum standards and criteria for the application of such standards for the pretreatment of specific industrial waste discharges. The provisions of this section shall not prohibit the city engineer from requiring additional pretreatment to accomplish the objectives of Section 13.08.080.
(Prior code § 5-4.1007.1)
No person shall place, throw, or deposit or cause or permit to be placed, thrown, or deposited in any public sewer or main line sewer any dead animal, offal, garbage, fish, fruit or vegetable waste or other solid matter, material or obstruction of any kind whatever of such nature as shall clog, obstruct or fill such sewer or which shall interfere with or prevent the effective use or operation thereof. No person shall cause or permit to be deposited or discharged into any sewer any water, sewage or liquid waste of any kind containing chemicals, greases, oils, tars or other matters in solution or suspension which may clog, obstruct or fill the sewer, or which may in any way damage or interfere with or prevent the effective use thereof, or which may necessitate or require the frequent repair, cleaning or flushing of such sewer to render the sewer operative, or which may obstruct or cause an unwarranted increase in the cost of the treatment of the sewage. Storm runoff waters shall not be discharged into a sanitary sewer.
(Prior code § 5-4.1008)
Garbage resulting from the preparation of food may be discharged into the public sewer if such garbage is ground to a fineness sufficient to pass through a three-eighths inch screen. Excessive or unnecessarily large quantities of water shall not be used to flush ground garbage into the sewer.
(Prior code § 5-4.1010)
The city engineer may authorize the installation of a rainwater diversion system in lieu of roofing to prevent the discharge of storm waters to the sewer system where roofing is impractical, in conflict with existing laws or regulations, may create a hazardous or unsafe working condition, or may cause undue hardship on the applicant, providing the city engineer finds that:
A. 
The applicant has applied for an industrial waste disposal permit and has submitted all plans and specifications of the proposed system;
B. 
The system provides for continuous twenty-four hour protection to the public sewer system;
C. 
The system meets the minimum operational and component standards as may be established pursuant to Section 13.08.090; and
D. 
The pollution of underground or surface waters or damages to any street, gutter, storm drain, channel, or public or private property will not be caused by the diverted storm flows.
